What is the torque for the head bolt?
What is the torque for the head bolt?
The medium-head bolts need 22 foot-pounds of torque and a 65-degree rotation. The long cylinder head bolts required 22 foot-pounds of torque and a 75-degree rotation.
What are the torque settings for head bolts?
SOURCE: head bolts torque settings According to my haynes manual for G-S reg, 1989-1998 it goes as follows, Stage 1:- Tighten all bolts by hand until bolt heads just contact cyl. head. Stage 2:-Tighten all bolts to 40Nm or 30lb ft. Stage 3:-Angle tighten all bolts a further 60 degrees. Stage 4:-Angle tighten all bolts again a further 60 degrees.
What is head bolt torque spec?
Torque, as a specification for head bolts, refers to the amount of rotational force required to tighten the bolts properly . Torque is measured in foot-pounds. Manufacturers provide torque specifications to guide mechanics in properly tightening the bolts connecting the cylinder heads to the main engine.
What does “torque to yield bolt” mean?
A torque to yield fastener (TTY) or stretch bolt is a fastener which is torqued beyond the state of elasticity and therefore undergoes plastic deformation, causing it to become permanently elongated. Fastener. Jul 10 2019
